CHARLES J. HIGGINS, OF I'IALLOWELL, MAINE.

LANTERN.

SPECIFICATION forming part of Letters Patent No. 417,026, dated December10, 1889.

I Application filed September 25, 1889. Serial No. 325.075. (N0 model.)

To caZZ whom it may concern:

Be it know that I, CHARLES J. HIGGINS, a citizen of the United States,residing at Hallowell, in the county of Kennebec and State of Maine,have invented a new and useful Improvement in Lamps and Lanterns, ofwhich the following is a specification.

This invention relates to that class of lamps and lanterns in which ametallic oilpot is .used, and has for its objects to simplify theconstruction of the burner and to provide simple means for indicatingthe height of the oil in the oil-pot.

My invention consists, to that end, of the improvements which will behereinafter fully set forth, and pointed out in the claims.

In the accompanying drawings, Figure l is a sectional elevation of thelower portion of a tubular lantern provided with myiniprovements. Figs.2 and 3 are horizontal sections in line 00 0;, Fig. 1, one lookingupward and Figs. 4 and 5 are sectional elevations at right angles toeach other of the filler of the oil-pot.

Like letters of reference refer to like parts in the several figures.

A represents the oil-pot of a tubular lantern; B, the air-chambersecured to the top of the oil-pot, and C O are supply-tubes which openinto the sides of the air-chain- D61.

D represents the fiat wick-tube, which is arranged within theair-chamber and seated with its lower portion in a slot formed in thetop of the oil-pot. The wick-tube is preferably composed of two parts orsections, the lower part cl entering the slot of the oil-pot, in whichit is secured by soldering or otherwise, and the upper part (1' beingdetachably secured to the lower part by a slip-joint or other suitablemeans, so that the upper part will remain securely in place on the lowerpart in the ordinary conditions of use of the lamp or lantern,but can beremoved from the lower part when the upper portion of the burnerrequires renewal and forothcr purposes.

E represents the perforated gallery or flange which surrounds the upper.portion of the wick-tube and is secured thereto by soldering orotherwise. This gallery is provided with air-openings of any suitableform, and has formed on it depending ears e e, in which the shaftGof thewick-raiser is journaled. These ears are preferably partially severed bystamping from the plate of which the gallery is formed, and are thenbent down. The wick-raiser shaft maybe arranged in notches g g, formedin the top of the air-chamber, on opposite sides of the burner, or itmay be arranged above the edge of the air-chainber.

H represents the burner-cone which surrounds the wick-tube, and whichrests with its laterally-extending base portions upon the air-chamber B.The base of the burner-cone is provided with a marginal flange h, whichoverlaps the top of the air-chamber. This burner-cone may also rest uponthe edge of the perforated gallery.

I represents the perforated plate which sur rounds the burner-cone, andJ represents the globe.

I-Ieretofore in this class of lamps and Ianterns the wick-tube wassurrounded by a is known as the slip-burner, or the jacket and socketwere provided with screw-threads and secured together. In either casethe burner occupied considerable space and obstructed the air-chamber inwhich it was arranged and from which the air passed upwardly through theperforated gallery to the flame. Furthermore, the slip burnerconstruction required devices for preventing the burner from turning inits socket, while the screw-fastening necessitated the employment of ajointed wick-raiser shaft in order to enable the wick-raiser to bearranged below the top of the air-chamber. It is also difficult in theseprior constructions to prevent the es cape of oil upwardly from theoil-pot, because both the slip-burner and the screw-burner have nooil-tight connection with the oil-pot. In my improved construction thejacket surrounding the wick-tube is dispensed with and the latter isinserted directly into-the slot formed in the top of the oil-pot. Thisenlarges the air-space in the air-chamber, prevents the burner fromturning, and permits a reduction of the diameter and height of theburner-cone and air-chamber, thereby reducing the height of the lamp orlantern. The construction of the burner and oil-pot is also muchsimplified and the costs of these parts materially reduced. When thewick-tube is secured in the slot of the oil-pot by soldering, no oil canescape upwardly except through the wick, and leakage is prevented.

represents the opening formed in the top of the oil-pot for supplyingthe same with oil, and K is the internally-screw-threaded collar whichis secured in this opening. K represents an eXternally-screw-threadedstopper by which this opening is closed.

L represents a float which is arranged in the oil-pot underneath saidopening, and which rises and falls with the level of the oil in theoil-pot, so that the rise of the oil-level can be readily observed infilling the oil-pot, and overflow at the filler-opening be prevented.This float is constructed of cork or other buoyant material, and ispreferably painted in a conspicuous color, so that it can be easilyseen. This float is hung by an arm Z to a hinge-axis M, secured to theunder side of the top of the oil-pot. The hingeaXis consists of a bentwire, which is formed or stop m, which holds the float slightly out of aperpendicular position toward the filleropening 70, so that the float iscompelled to rise toward the filler-opening, and is prevented fromrising on the opposite side of its pivot, where it cannot be seen.

My improvements are particularly desirable for use in tubular lamps andlanterns; but some of them may be advantageously applied to lamps andlanterns of other styles.

I claim as my invention 1. The combination, with the oil-pot havinganelongated opening in its top, of a flat wick-tube seated in saidopening, an airchamber secured to the oil-pot and surrounding saidelongated opening, air-supply passages communicating with saidair-chamber, and a burner-cone surmounting said Wicktube andair-chamber, substantially as set forth.

2. The combination, with. the oil-pot hav wick-tube seated in saidopening, an airchamber secured to the oil-pot and surrounding saidelongated opening, air-supply passages communicating with saidair-chamber, a perforated gallerysecured to the Wick-tube andsurrounding the same, and a burner-cone ing an elongated opening in itstop, of a flat surmounting the wick-tube and resting upon theair-chamber, substantially as set forth.

3. In a tubular lantern, the combination, with the oil-pot, of anenlongated socket attached to the oil-pot, and a removable elon gatedwick-tube seated in said socket,whereby the Wick-tube is kept fromturning, substantially as described.

4:. The combination, with the oil-pot having an elongated opening in itstop, of a wicktube composed of a lower portion permanently secured insaid opening, and a detachable top portion, a perforated gallerycarrying the wick-raising shaft secured to said top portion, and aburner-cone, substantially as set forth.

5. The combination, with the oil-pot having an elongated opening in itstop, of a wicktube composed of a lower portion permanently secured insaid opening, and a detachable top portion, a perforated gallery securedto said top portion, an air-chamber secured to the oil-pot andsurrounding said elongated opening, air-supply passages communicatingwith said air-chamber, and a burner-cone resting upon said air-chamber,substantially as set forth.

(5. The combination, with the oil-pot and the wick-tube secured thereto,of a perforated gallery secured to the wick-tube and provided with ears,and a wick-raiser shaft journaled in said ears, substantially as setforth. at one end with a downwardly-extendin g arm 7. In combinationwith an oil-pot having ;an elongated opening in its top, an elongatedwick-tube arranged therein, said wick-tube carrying a shaft andratchet-wheels for raising the wick, an air-chamber formed by the top ofthe oil-pot, side walls, and the cone .with its supporting-plate, saidwheels being inelosed and protected therein, air-tubes entering the saidair-chamber, and the globe surn'iounting the. said air-chamber,substantially as described. v

8. In a tubular lantern, the combination,

with the oil-pot having an elongated opening in its top, of an elongatedwick-tube arranged therein, whereby the position of said wicktube iskept in its proper relation with the airtubes and other parts of thelantern, an airchamber on top of the oil-pot and surrounding saidopening, air-tubes connected with said air-chamber, and a burner-conesurmounting said air-chamber, substantially as described.

WVitness my hand this 21st day of September, 1889.
